MACHINE FOR CARDING FLOOCULENT MATERIAL.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed May 2 9, 1909. Serial No. 499,217.

To all whom it may concern:

Be it known that I, JOHN ALLEN HEANY,

I a citizen of the United States, residing at York, in the county ofYork and State of Pennsylvania, have invented certain new and usefulImprovements in Machines for Carding Flocculent Material, of which thefollowing is a specification.

My invention relates to a machine for carding flocculent material suchas asbestos, and delivering it to a Wire to be coated therewith.

In U. S. Letters Patent No. 825,124, granted to me under date of July 3,1906, there is described a machine, which will sufficiently illustratethe general type of mechanism to which this invention relates.

Referring to the drawings: Figure 1 is a side view of the mechanism;Fig. 2 is a plan view of the same mechanism; and Fig. 3 is a detail viewof the combing device.

Referring more particularly to the draw ings, 1 is an open-bottom hopperfor containing the flocculent asbestos. Arranged to rotate within thebottom of the hopper is a wheel 2, having on its periphery card teeth 3.

4 is a metallic comb rigidly secured to a block or bar 5, having at eachend thereof rollers 6, which roll in grooves 7 in guide plates 8 carriedon brackets 9, which brackets are in turn mounted on side bars 10 of themachine frame (not shown). Journaled in one of the plates 8 is a shaft11 having at its outside end asprocket-wheel 12, and at its inner end acrank-arm 13, having a crank-pin 14, to which is attached a pit-man 15,secured to the bar 5. The sprocket-wheel 12 is driven by a suitablechain 16, and sprocket-wheel 17, mounted on the shaft of the card-wheel2. Also mounted on the shaft of the wheel 2 is a bandpulley 18, aboutwhich is a driving belt 19. This belt 19 passes around a belt-wheel 20of larger diameter than the band-pulley 18, which is secured to theshaft 21 of a second card-wheel 22.

Mounted on the sides of the hopper are brackets 23, only one beingshown. This bracket 23 has a slot in its outwardly bent flange 24,within which slides a sheet-iron guard-plate 25, pivotally connected atits lower end to the comb-plate 4. The plate 25 serves as a guard-plateto prevent the fibers from getting behind the comb-plate 4.

Fig. 3 illustrates the successive positions assumed by the comb-plate.

The operation of the device is as followsz-The card-teeth of the wheel 2seize the asbestos fibers and carry them under the comb-plate 4, which,because of the peculiar motion given to it, effectively combs out suchfibers. The block or bar 5, which carries the comb-plate 4, owing to thecrank and pitman connection is given a reciprocating movement in thegrooves 7 and at the same time oscillates about the rollers 63, whichare in effect pivots. As will be apparent from the diagram shown in Fig.3, the comb-plate assumes the successive position shown, 2'. 6., as itmoves downward and toward the card teeth of the wheel 2 but in anopposite direction, it combs out the fibers held by the coacting cardteeth; it then moves backward and away from the card teeth, but in thesame direction as the cardteeth on the wheel 2, to disengage itself fromthe combed out fibers. The combed fibers are carried forward on theperiphery of the wheel 2, until they are picked off. by the card-teethon the periphery of the wheel 22. As this wheel 22 rotates more slowlythan the wheel 2, the fibers are thus still further combed, and are thenready for delivery by the wheel 22 to the wire 23,which has been coatedwith a suitable adhesive to cause the fibers to be licked off asdescribed in my prior patent. If finer combing is desired, additionalcard-wheels may be added.

What I claim is 1. In a machine of the class described, a cardingmechanism comprising a hopper for containing the flocculent material, acardtoothed roll arranged to rotate therein, a comb arranged tocooperate with the teeth on the roll, and means for imparting a combinedreciprocating and oscillating motion to the comb.

2. In a machine of the class described, a carding mechanism comprising ahopper for containing the flocculent material, a cardtoothed rollarranged to rotate therein, a comb arranged to cooperate with the teethon the roll, means for imparting a combined reciprocating andoscillating motion to the comb, and a second card-toothed roll arrangedto cooperate with the first-mentioned roll.

3. In a machine of the class described, a

carding mechanism, comprising a hopper for containing the fiocculentmaterial, a cardtoothed roll arranged to rotate therein, a comb arrangedto cooperate with the teeth on the wheel, a block to which said comb issecured, guide plates having slots therein, pivots connected to theblock and arranged to move in the slots, and means for reciproeating andoscillating the block.

4. In a carding mechanism, the combination of a comb, a block to whichsaid comb .is secured, stationary guide plates having slots therein,pivots connected to the block and arranged to move in the slots, meansfor Copies of this patent may besobtained for five cents each, byaddressing the Commissioner of Patents,
